Technical Support Package for Tech Brief 68-10507: Electronic Component Reliability by Data Reduction System Analysis

摘要

The purpose of the Data Reduction and Presentation Task was to develop a merchanized data reduction system to evaluate test results from electronic parts screening. A comprehensive plan was developed for mechanized processing of screening data. The plan provides maximum utility with minimum cost and inconvenience to the parts supplier. The new data format specification controls the input data problem while providing a high degree of format flexibility. The flexibility permits suppliers to use familiar data recording techniques and thus promotes raw data accuracy. The computer processing system has been designed to meet three basic objectives: (1) To assess vendor test data and confirm parts acceptability; (2) To describe test results in the form of parameter distributions, means, and standard deviations; (3) To determine technical trends such as lot-to-lot variability and vendor performance. To date, the design of the first phase is complete and computer programming for the IBM 7994 computer is approximately 70 percent complete. Design of the balance of the system has begun. Programming of the Phase 1 system, performed by another contractor, will continue during the expected delay period prior to resumption of design work. (Author)
